Hyperbolic / Inverse-Hyp. functions
SR-281 / SR-282 uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse-hyperbolic functions - sinh, cosh, tanh, sinh
–1
,
cosh
–1
and tanh
–1
.
(Note) : When using those keys, make sure the calculator is set for the
angle unit you want.

)
(Note) : When using those key, make sure the calculator is set for the
angle unit you want.
The calculator can perform the conversion between rectangular
coordinates and polar coordinates by [ 2nd ] [ P
R ] and [ 2nd ]
[ R
P ].
